We have recently had a few clients who have experienced some issues with PoE plugs on the pigtail of their Hik cameras, which resulted in the PoE connector failing to supply power / transmit signal.
Typically, the problem appears after the PoE connector has been used outdoors for a couple of years without a proper waterproof insulation. Less often, the issue can be caused by physical damage, faulty waterproof and simple wear and tear.
Unfortunately, Hikvision does itself provide any spare PoE connector replacements, so you will have to do a bit of a workaround. The process itself is, however, quite simple and does not require any prior engineering experience.
So, here we will look at what you need to do if you have this issue.
Step 1 – Make sure that you have all the necessary tools
To get your camera up and running, you will need:
Punch Down tool
Cat5/6 Junction Box (punch-down type)
Step 2 – Cut off the faulty PoE Connector
Using a utility knife (or just a sharp knife) snip off the PoE connector on the camera, ideally as close to the connector itself as you can to leave you with a long enough cable.
Step 3 – Strip an inch of the cable
Using the crimper, strip back an inch of the cable to expose the 8 coloured wires within.
Step 4 – Identify your wiring colouring
Depending on the model you have the colouring may not follow the standard colouring, so you need to work out what wire colouring your model follows.
You will need to use the wiring pattern of the T568B standard.
Older Hikvision devices use the following colouring:
Newer models may have the following colour scheme correspondence:
Step 5 – Punch the wires into the corresponding slots
Using the punch-down tool, place the exposed wires into the corresponding slots in the junction box (using the colour scheme tables above). The end result should look something like this.
Step 6 – Connect the other RJ45 to the junction
To complete the process, connect the other network cable to the junction.
